HEAD .FOR BTTLE-CAPPING MACHINES..

Specification of Letters Patent. Patented Oct, v26, 1909.

Application filed January 29, 1909. Serial No. 475,006.

To all whom 'it may concern:

le it linown that l, liolns C. KRUMMEL, a citizen of the United States,residing at Clinton, in the county ol" lvliddlesex, State ofConnecticut, have invented. certain new and useful Inlprovements inlleads for Bottle-Capping h'lachincs, hf which the following is adescription, reference being had to the zweonipanying, drawing, and tothe iigures of reference marked thereon.

The invention relates to machines for capping bottles, and moreespecially to that class of machines in which the nietal cap is placedon the inout-h of the bottle, and the flange of the'cap is turnedumlerneath the shoulder at the mouth ofthe bottle, thereby securing theea p to lsaid bottle.

An object oi the invention is to provide a head for a machine oi theabove cl'iaracter, which head shall b e durable in construction andeiiicient in operation.

A further object of the invention is to provide a bottle-capping headwith means for securing the cap to the bottle, which nieans includesdevices for lil'niting the nnwelnents of the parts, so that undue orbreaking pres sure will not be applied to the mouth of the bottle,during the closing of the cap.

A further object of the invention is to provide a'bottle-capping headwhich includes a cap-receiving chuck, movable longitudinallyindependently of the head.

A further object of the invention is to provide a bottle-capping headwith a cap-receiving chuck and with an ejector, for fore-- ing thecapped bottle out of the chuck.

A further obj ect of the invention is to provide a bottle-capping headhaving a' chuck which is movable longitudinally in the head, and a capejector, which head is so positioned relative tov the 4cap-holding'devices that the ejector and chuck serve to 4steady the cap and hold thesanie on the bottle until properly received by thehead.

These and other objects will in part be obvious, and will in part behereinafter more fully described.

In the drawings, which show by Way of illustration one embodiment of theinvention,-Figure 1- Iis a sectional view through my improved head; alsoshowing` its relation to a cap-holding device; Fig. 2 is a sectionalview on the line 22, yof Fig. 1; Fi 3 is a sectional view of certainpartsof the head, showing the head expanded, that is, with the innerlsleeve -inoved to its extreme position out of the outer sleeve-g Fig. 4is a side elevation of the head; Fig. 5 is a sectional detail, showing amodified form of the invention in that the ejector is positivelyoperated. `Fig. is a View similar to F ig. 1, showing a lnodiicalforlnlot' chuck support. Fig. Tis a detail of the housing for the springs.FigzjS is a view on the line 8 8 of Fig. 7; and Fig. 9 1s a detail Viewof the chuch-operating device.

The entire head 1, as herein shown, is carried by a spindle 2, which maybe the spindle oi any suitable bottle cappino' machine, orot any othermachine that will give the head. a( rapid rotary motion.

ln Fig. 1, the bottlecapping head is shown asV rotating above acap-holding device 3, which cap-holding device may be a part otA anysuitable automatic cap-feeding nieclnuiisln. It will be obvious,however, that from certain aspects of the invention, the bottle-cappinghead may be used With. out any cap-feeding device, the caps being placedby hand on the bottle, which is inserted intothecapping head.

My improved capping head comprises an outer sleeve 4, which is-threadedon to the spindle Said outer sleeve is recessed to receive an innersleeve 5, which is connected to the outer sleeve by a spline (i, so thatthe inner sleeve may inovc into and out ot the outer sleeve, but Willrotate with the outer sleeve.

Arspring 7. is located in aout out or recessed portion 8 of the spindle2, and at one end bears against the spindle, While at its other end saidspring bears against the inner sleeve.l The spring 7 will normally holdthe inner sleeve in the position shown in Fig. 3, that is, Withdrawnfrom the outer sleeve, until the shoulder 9 engages the cap plate 10carried bythe outersleeve. `In this position the head may be said to beexpanded.

The inner sleeve is provided With a central recess in ,Which is mounteda'chuck 11. The chuck is threaded on ,to a sleeve 12. The sleeve 12extends throughs collar 18,y which is threaded intothe innerl sleeve 5.Thein- 'i vner sleeve is provided with a shoulder 14 and a ball bearingrests on the ,shoulder 14, and is engaged at its upper side by thecollar 13. The collar 13 is also 'pmy-ided with a reduced portion 16,which extends tates la down into the ball bearing 15. The reducedportion 16 terminates a. short distance above the lower side of the ballbearing.

The chuck 11 slides freely in the inner sleeve 5, and remains stationaryduring the cappi operation, while the inner sleeve rout the saine. Whenthe chuck is in itsinnermost position, as shown in Fig. 1, it engagesthe ball bearing, which takes the end thrust caused by the forcin of thebottle up into thecapping head. ,'Iie sleeve 12 which carries the chuck11, is provided with an enlarged head 17, which engages the upper faceof the collar 13, and limits the downward movement of the chuck relativeto the inner sleeve. A spring 18 entlie sleeve 12 at one end, and acollar y 19 at the other end, and operates tol norinalll'y hold thechuck in the position shown in i 17 of the sleeve 12 against the upperface ofthe collar 13. r

kThe chuck 11 is provided with aL bottlecap-receivin recess 20, which isconstructed 'so as to con orin to the shape of the cap being secured tothe bottle. The chuck is also provided with a further recess to receivean ejector ypad 21, carried by a stem v22, extending up through acentral opening in the chuck, and which isv provided with anenlargedhead 23 at its upper end, which engages av shoulder 24 formed inthe central recess of the chuck, so as to limit the 'downwardA movementof the ejector pad. An ejector rod 25 extends centrally through saidhead, and throu h the supporting spindle 2. The collar 19 a ve referredto, is carried by said ejector'rod. -The ejector rod at its lower endhas a reduced portion 26,'having a rounded end normally bearing againstthe upper enlarged end 2,3 of thestem 22. A

spring 27 surrounds the reduced portion 26 of the ejector rod, and bearsat one end against the shoulder on the ejector rod, and at the other endagainst thehead 23 of the Y stem 22.

The vcollar 13, which bears against the er face of the ball bearing 15,may be adjusted, owing to its threaded connection with the inner sleeve;As a means for hold-` ing said collar in its adjusted posit-ion, I

-have provided the collar with a plurality of semicircular recesses 28.The inner sleeve has also a vsimilar semicircular recess 29. The collar13 is turned until one of the rccesses is brought opposite thesemicircular recess 29, after which a screw or pin 30 may be inserted,to hold the collar 13 against accidental movement in the sleeve.

The closing roller 31 is herein shown as a corrugated crimping roller,although it is obvious from certain aspects of the inven` tion, thatsaid roller might be a smooth surface roller for spinnino` the materialof the cap underneath the flange on the bottle.

g. 3, that is, with the enlarged head The crimping roller 31 is mountedto rotate freely on a stud 32, carried by a'lever 33, pivotally suported by a rod 34, carried by the inner s eeve. The-'inner sleeve isrecessed' in order to provide a space for the supporting lever 33.` lheouter sleeve has also a recess, in which is located a bar or plug 35,having at its upper end an enlarfrcd head 36, and having its lower endrounded to engage a similar rounded socket in the laterally projectingarni 37 of the lever 33. A spring 38 engages the upper end of the bar orplug 35. -A screw is threaded into the upper part of the recess in theouter sleeve, and serves as an abutment for the sprinni 38.

The ejector-operating rod` 25 may be spring pressed or may be positivelyoperated. In Fig. 5 of the drawing, I have shown a slightly modifiedform otpconstruction of ejector-operating means. In this figure, theejector head 40 is 'threaded direct y onlto the end of the ejector rod41. The ejector rod extendsl u through the supporting spindle for thecad, and at its up er end is rovided with a split nut and kni'ic le 42,which is pivoted to the lever 43.

In the operation of my device, the bottle is yinserted up through. thecap-supportin device, which carries a metal cap provide with a packing,generally consisting of disks formed of a yieldino' material such ascork,

which will not be affected by the contents of.

the bottle.- The capping head, which is rotated continuously with theexception of the ejector pad, the chuck andthe ejector rod which arestationary, is located directly above the cap-supporting device, and thearts are normally in the osition shown in ull lines in Fig. 3, and indotted lines in Fig. 1. In thisvposition it ,will ibeobserved..

that the ejector pad is located directly` above the cap, so that as soonas the bottle engages the cap and raises the same from its seat in thesup Lort for the'cap, said cap will be engaged by the ejector pad;i andheld on the mouth of the bottle, and yrop- .erly directed into thereceiving recess i the chuck. The chuck is also forced oiittvard fromthe capping head, and lies `in a position directly above the support forthe cap. After the cap has been seated in thereceiving recess of thechuck, a further upward movement of the bottle carries the chuck andtheejector pad up into the inner sleeve, which, as the capping head isexi,- panded, rests on the cap plate 10 ofthe outer sleeve. The crimpingroller 31isat this time, thrown back or to the right, as shown in Fig.3, by re'ason of the fact that the innersleeve is moved down out of theouter sleeve, carrying with it the supportinglzlever 33, and the arm 37of the lever 33l has engaged the cap .plate 10, which throws thecrimping roller -to theposition stated.

izo

isok

sleeve against the action of the spring 7.

-ing wheel is also a yielding movement, for

vbring aboutthe movements above stated.

A further upward movement of the bottle. forces the inner sleeve up intothe outerv As the inner sleeve moves upward, the'lever carrying thecrimping roller 31 also moves upward, and the arm 37 contacts with theplug or bar 35, which rotates the lever 38 about the supporting pin 34,and brings the crimping roller 3L into contact with the iange of the capextending beneath the shoulder or. the mouth of the bottle. vlnasmuch asthe head is continuously rotating, the crimping roller will be carriedaround the mouth of the bottle, which, together' s with the chuck andejector pad, is stationar thus graduallyl turning the flange of the capunderneath the shoulder on the bottle. When the inner sleevecontacts-with the outer sleeve at its .'uppei'iel'id, a further movementof the inner sleeve upward is pre-l vented, and, therefore, the inwardmovement of the crimping wheel, that is, the movement of the crimpingwheel into contactwith the flange of the cap, is positively limited.This inner movement of the crimpthe reason that the` plug or bar 35 mayyield to the action of' the spring 38. lf, therefore, there should be anunevenness in the formation of the mouth of the bottle, so as to cause abreaking of the bottle, due to the excessive strain ofthe crimping wheelon the bottle, said crimping wheel would yieldto allow the unevenportion of the bottle to be properly passed. lt will be seen, therefore,that l have provided a device wherein the cap may be properly crimpedand secured to the bottle, regardless of any uneven parts in the mouthof the bottle, and that'the force with which the flange is l turnedunderneath the shoulder on ythe mouth of the bottle may be adjusted byadjusting the screw 39, thus avoiding` the breaking ot the bottle.

After the cap has been secured to the bottle, the bottle is withdrawnfrom the -apping head, and the inner-'sleeve will first move out of theouter sleeve, after-which the chuck will move out oi the inner sleeve,and after the chuck and inner sleeveI have reached the limit of theirdownward movement, the ejector pad-will operate to force. the cappedbottle out of the recess in t-he chuck. The movement of the ejector' paddownward, relative to the cap-supporting device is snilicieiit.` toforce anybroken portions ot bottle down through the cap-supportingdevice, so as toprevent any clogging ot the apparatus.

li the ejector pad is operated positively, as shown in Fig. 5, the camfor operating the same will,`of course, be so timedasto That ijs, toallow the head to be expanded be'- fore' the bottle forcel from 'thechuck.'y

In Fig. G the spindle is a rotating spindle carrying the outer sleeve 4and inner sleeve 5, vwhich are of the same construction as thatdescribed in connection with Fig. -l, and the same reference numeralshave been' applied to the partst-hercof, The

chuck l1 is threaded on to the endof'a rod 44, which extends upv throughthe rotating spindle 2. Said chuck is recessed to receive the ejector'23, which is held normally forced out from the chuck'by means ofafsnitable spring 45, located in a recess `formed in the end of the rod44, as shown in dot-ted lines in Fig. 6.' The spring 7, which holds "thecrimping head expanded rests at its upper end against a collar 46 which1s secured to the spindle 2 by suitable pins 47. 'The rodl 44 is thraded and provided with an adjust-v able threaded collar 48. :Asemi-cylindrical member 4t), is provided with perforated projecting ends50, which slide over the rod 44. Said member 49 fits the inner bore ofthe spindle 2. The collar 48' is cut away as at 51, so that said collaris formed with shoul-.

ders 52,which, when the .opening in said' collar is in alinement withtheopenings in the enlarged ends 50, rest.A against the edges of thesemicylindrical 'member 49. The collar 48 is adjustla'bly secured to therod 44, and by the shouldered connection with the cylindrical member4f), said member is. held from rotating with the spindle A spring 53surrounds the rod 44.l and rests normally at its lower end against thelower enlargedhmul' 50 of the cylindrical.

member 4f). A spring 54 also surrounds the v rod 44 and is locatedbetween the upper tace of the collar 4S, and the upper enlarged end 5()of the semieylindrical member 4S). In the operation of my device, 'thecollar 48 is so adjusted that when said collar rests uponl the spring53, thcchuck 11 is positioned as shownin Fig. (3, that is, said chuckextends into the cap-fecding head, but is held at a suilicient distanceabove the ledge or shelf supporting the caps, topermit said caps to befreely fed underneath said chucks. lVhen a bottle is raised into contactWith. the ca "i, it is at once carried' into the recess terme in thechuck mving the ejector 23 up into its recess compressing the spring 45;A further upward'movement of the bottle causes the collar 48 to compressthe spring 54, and allows the chuck 11 to engageA a ball bearingsupport, to cause the inner sleeve to move up into the outer sleeve inpre.

cisely the same manner as hereinbefore dcscribed. W hen the bottle 1slowered after having been capped, the spring 54willmove` the rod 44, andthe chuck 11, downward with the bottle.. The collar @.48 ,contacting-with the spring 53, limits the downward movement of the rod 44 and thechuck, and

holds the chuck in What-may be called itsv normai position. Ananti-friction; washer or ball bearing 55 v,apports the semicylindricalmember 49, and allows the spindle to rotate freely about said member. ll

In order to remove any broken caps or broken pieces of caps from thecapping head, I may provide my capping head with means for moving thechuck down into the capping head to a point below the ledge on which ling the spring 53. reaches its `lower position,

receiving chuck the caps normally rest, and thus positively .fo ce outof the capping head all said broken arts.- As herein shown, the rod 44is provided with a split collar 5G, carrying pins 57, to'which ispivotal-ly connected a lever 58, fulcrumed at 59 upon any suitablesupport. A rod 60 having a collar' 61 secured thereto, passes through anopening in an enlarged portion of the lever 58, and said rod may begiven a downward movement at the proper time l to be fed underneath thechuck.

If my device is applied to a machine wherein the sameis stopped aftereach capping operation, the positive operation of the chuck should, ofcourse, occur before the machine stops. By adjusting the rod 44 in thethreaded collar 48, the normal position of the" chuck may be varied. Y
